The prime Eel grass on the Exe is Zostera nolti which stabilises sediment, provides organic matter and shelter and is a surface for attachment by other species such as small snails.  It is an essential habitat for Wigeon and Brent Geese who feed on the Exe Estuary's Eel grass.

The Eelgrass acts as a nursery for small fish and crustaceans, such as plaice and prawns, who feed on the algae attached to the leaves and shelter from predators.  These are prey for a number of bird species including the rare Slavonian Grebe.

The Eel grass beds are an essential habitat on the Estuary and making it important to monitor their condition abundance.  The Environment Agency will be carrying out a survey of the Eel grass beds later this summer.
